SPECIFICATION forming part of Letters Patent No. 339,518, dated April 6, 1886.

Application filed September 2.9, 1884. Serial No.144,24?. (No model.) Patented in England July 19, 1884, No. 10,330; in Victoria October .3, 188-1, No, 21,854; in New Zealand November 20, 1884. No. 1,300; in South Australia February 3,1855, No. 5:31, and in New South Wa'cs February 3, 1895, 1,008.

To all whom it may concern.-

Be it known that we, WILLIAM It. BAKER and HENRY E. Pnimronu, both of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Grain-Binders, of which the following is a specification.

A type of binder manufactured by the Mc- Cormick Harvesting Machine Company during the past season, and well known in this country, may be referred to in illustration of these improvements, although some of their features will be found applicable to machines differing in structure. In such type the grain was received upon a platform-apron, carried up an elevator at the inner end of this apron, and discharged into a descending chute or covered passage-way, where it was urged forward wisp by wisp or bunch by bunch by alternatin g packer-arms against tripping-fingers which closed the outer side of the chute. A section of the decking in the chute was hinged at the top and connected with the tripping devices, so that in case the grain lodged in the passage-way before reaching the trip-fingers it might press upon this section and thusstart the trip. One of the packingarms operated through a slot in the hinged section, while the other arm operated through a slot in the stationary part of the decking. The trip-clutch on a shaft operated from the harvester was connected with the trip-fingers and hinged section or table-trip, as it is called, so as to be thrown into engagement with a loose pinion on said shaft by the starting of either or both of these tripping agencies, and this pinion when engaged drove by means of two intermediate idlewheels agear and cam wheel on the binder-shaft, whereby the knotter, holder, and cutter, the binding-arm and the support for the outside trip-fingers were actuated. A slack-lever controlled by a cam on one of these idle-wheels was also employed to take up or give out slack in the cord at proper intervals.

The present invention relates to improvements in the frame of the binder, dispensing with the cumbrous wood-work of the former construction, and in place thereof uniting the metal parts heretofore used by light metal ties and castings or transverse bars; to a novel construction of the table-trip; to changes in the manner of mounting and controlling the finger-trip and in its connection with the table-trip; to the slack-lever and tension which are herein made to co-operate by a single spring, and the former of which serves to lock the wheel that carries its controlling-cam whenever the binder is out of action, in order to hold the mechanism. steady and in place until tripped; and to various other features, combinations, and details of construction hereinafter described and claimed.

In the drawings. Figure l is a skeleton side elevation ofa binding attachment embodying this invention, the wind-board or buttapron and part of the framework being removed to more clearly expose the operative mechanism. Fig. 2 is a plan view of the same, including the frame; Fig. 3, a top plan view of the frame with the operating parts removed; Fig. 4, a front end elevation of said frame under like conditions; Fig. 5, astnbble side elevatiomaiso with operative parts removed; Fig. 5, a side elevation of the transverse metallic frame-bars with the extension of the front bar beyond the other represented in dotted lines; Fig. 5", a plan View of said bars with same representation; Fig. 6, a detached view of the table-trip arm; Figs. 7 to 12, enlarged details of the outside tripping-fingers and mechanism immedi ately accessory thereto, to explain the manner in which they are rocked back for the discharge of the bound sheaf, and in such rocking actuate the hinged leaf or tail-board at the foot of LIA the chute; Figs. 13 and 14. detached views enlarged, in elevation and plan, respectively, of the slack-lever and tension; and Figs. 15 to 17 ,enlarged details of said lever and tension.

A represents the post-frame or main bracket having one arm or sleeve, a, overhanging the binding-table or grain-chute and serving as abearing or support for the binder-shaft, and a second arm or sleeve, (1, subtending said table or chute and receiving the rock-shaft which carries the binder-arm. These tubular arms vertical flange or web, a", bored at two points, a and (L to receive stub-axles for the two idle-gears in the train communicating motion to the binder-shaft, and from the lower or subtending arm project ears or lugs a a",at an angle to said post determined by circumstances, but here shown as slightly obtuse, the lug c being in other respects, however, a substantial extension of thepost and advisably further united therewith by integral connection through the just mentioned vertical flange, as shown. Opposite to these lugs are other lugs, a a, in the same plane therewith, and also integral with the post-frame, and these latter, as well as the lug a are preferably strengthened by webs from the subtending arm and post formed in the process of casting.

Bolted to each pair of lugs or ears thus provided are transverse bars 13 B, of cast metalmalleable iron or steel, for instance-which on the outer or stubble side of the arm have each a hearing, I), for the reception of a rockshaft, which carries the tripfinger, as presently described, and on the inner side are first bent downward or away from the plane of said ears, and provided with other bearings,

. b, for the packer-shaft or that shaft continuously driven from the harvester, then from these bearings rise upward until they reach and saddle a tubular frame-bar, G, such as heretofore used for like purpose, to which they are secured by through-bolts, as shown. At their lower or outer ends, just inside the shaft for the tripping-fingers, they also saddle and are similarly secured to a second tubular frame-bar, 0, extending parallel with the oth er from front to rear of the binder-frame, and beyond this last connection and outside of said shaft the bar B, which is the rearmost and lies alongside the plane of movement of the binder-arm, has a bracket extension, 0, in practically or nearly the same plane with a like oii'set or bracket, 0, from the subtending arm or sleeve of the post-fran1e, these two affording seats for the chute-decking or bindingtable. Other brackets, 0 are bolted to the frame at suitablepoints for the same purpose. Both transverse bars have also a pendent ear, inside of and in close proximity to the postframe, to receive and support the tripping rock-shaft; but these cars may, if desired, be formed integral with said post-frame.

At the junction of the front transverse bar with the upper tubular bar, and preferably by the same bolt uniting the two, is secured one .end of a brace-bar, D, of strap-iron or other suitable metal, which extends from this point to the upper stub-axle on the post-frame web, thus tying the post-frame firmly. The tubular frame bars are further united in rear of the binder-arm by two wooden cross-pieces or timbers, E E, the lnner one of which supports a bearing-bracket, e, for the rear end of the packer-shaft, this, in machines of the present type, being the one continuously driven from the harvester and on which the trip-clutch is mounted. Instead of wood, metal can be readily used in place of these timbers; but as the metal frame-work already provided gives great strength and rigidity to the whole construction they have very little strain or labor to support, and light wooden bars, such as shown, are consequently quite sufficient in their position.

Brackets F, bolted to the outer elevatorstruts, near their head ,reeeivein suitable seats a tubular supporting-bar, F, which is firmly secured in place, and guides or keepersf, from.

this bar, embrace the upper tubular frame-bar and permit it to slide longitudinally, as demanded by the adjustment of the binder. The lower tubular frame-bar rests upon properly grooved anti-friction rollers g, borne at the upper end ofstandards G from the end sill,G-', of the harvester-frame. Yokes or keepers g, projecting from these standards above the rollers, confine the bar against lateral displacement, and metal rods from the sill, hooked in and clamped to ears from the standards, which are themselves of metal, serve to brace the latter. This method of supporting the binder-frame has, however, been made the subject of an application filed as Division B of the present, on the 12th day of August, 1885, Serial No. 174,209, and is therefore not herein claimed.

Proceeding now to the description of the improvements in the binding apparatus proper: This, as heretofore, may be driven by a cranked packer shaft, H, journaled in the frame, as already described, and having a tripping-clutch, h, ofwell-known construction. A loose pinion, h, upon the end ofthis shaft,

locked thereto whenever the clutch is tripped,

communicates motion through the idle-gears h h, mounted upon the stub-axles from the post-frame web, as stated, to the gear and cam wheel H, on the binder-shaft If, and by this wheel all the positive movements ofthe binding devices are produced.

A trip-shaft, I, is mounted in the bearings provided therefor in the transverse framebars, and when rocked in the suitable direction operates, by means of a crank or lifter at its end, to raise the trip-dog I against the force of the spring 2', by which it is held down, and thereby disengage it from the clutch and permit the latter to grasp the driving-pinion. A shoulder, 2', upon the hub of the dog, is arranged to come against a counter-shoulder, i ,v from a collar embracing the binder-arm shaft 45 which latter forms the pivot for the dog, thus guarding against the latter falling beyond the point at which it should engage with the clutch. The spring i, as usual, is coiled about aguide-rod rising from the actuating-crank 1, on the end of the binder-arm shaft.

Instead of the hinged wooden table-section formerly adopted, a narrow forked or slotted metal frame, K, is employed, the two side bars of which extend ialong the side of and withinthe slot in the deckingfor the play of the binder-arm 7c, and lie one on each side of IIO the latter as it rises. This frame is hinged to a bracket, It, from the upper tubular framebar, which is practically at the head of said slot and extends down therefrom until its lower end,which is for this purpose somewhat narrowed, reaches and passes between the out side trip-fingers, being free to play up and down therebetween. It rests upon an arm, le from a casting affixed to the rear end of the trip rock-shaft, so that when depressed by the accumulation or obstruction of grain above it it will force down said arm and rock the shaft to disengage the trip-dog. On the binder arm shaft, which it will be understood subtends the grain table or deck, or on the hub of the binder-arm is a cam or lugyk in such position that as the arm rises and approaches the end of its ascent in the binding operation following the engagement of the trip-clutch, it strikes against the under surface of the metal table-trip and lifts it to give an additional compression to the sheaf over that given by the packers and binding-cord.

In order to bring about co-operation between the table-trip and the outside compressing-fingers, the casting or sleeve from which the already-mentioned triparm k" extends inwardly and upwardly until it comes againstthe underside ofthe table-trip to support the latter and respond to its movements, is provided upon the opposite side of the tripshaft with a second arm, k, extending ontwardiy to one side of and beneath the pivoted trip-fingers L, where it rests upon a lug, Z, from a heel-extension of one or both, so that as said fingers are pushed back upon their pivot they will lift this second trip-arm and rock the trip'shaft while the table-trip, if itself depressed, will push down the opposite arm, rocking said shaft in the same direction. Thus the trip'dog will be unlatched from the trip-clutch by the proper movement of either of these devices under pressure of the grain.

The trip-fingers are bolted to a skeleton block, 6, having an arched crown with longitudinal and transverse slots. A tongue, Z", from the base of the fingers takes into the transverse slot or slots, while a clamping-bolt, 1 passes from said base through the longitudinal slot. Thus by loosening the bolt the fingers may be adj usted in and out along the block to diminish or increase the grain-receiving space and consequent size of the gavel. The block Z,which in, this instance forms the above-styled heelextension of the fingers, instead of being pivoted upon supporting-arms hinged to the heel of the binder-arm and sus tained by links from an underlying rock-shaft, as heretoforc,is mounted directly upon a rockshaft, M, supported in the outer bearings of the transverse frame-bars and subtending the bindingtable near the outer edge of the latter,and plays upon said shaft as a pivot. The links m,which control the heels of the packerarms on, are also pivotally suspended from this shaft; but the packer-arms themselves are driven in the usual manner by direct connection with cranks m on the driving-shaft.

Keyed fast to the shaft which carries the trip -fingers, and alongside the supportingblock or heel-piece of said fingers, is a casting, N, having a lateral pin or log, n, which takes into a lateral slot, n, in said heel-piece, and a radially-extending arm, n link-connected with the tail-board O of the binding receptacle, so that Whenever the shaft is rock ed said casting may both swing the tripfingers back with it and open the tail-board. To this swinging movement the trip arm from the trip rock-shaft resting simply upon an open lug and not within a closed eye, as heretofore, affords no obstacle. A crank, 0, on the end of thislast-mentioned rock-shaft, is connected with the gear and cam wheel by an elastic pitman, 0, and T-head 0, similar to the one formerly used for opening and closing the aforesaid supporting-bar, so that when the binding mechanism starts the shaft will be operated by the action of said cam-wheel.

As the connection between the trippingfingers and the casting fixed to the rock-shaft is by slot and pin, said fingers are permitted to swing back on the shaft under the pressure of the incoming grain a sufficient distance to start the trip, provided they are previously held in such position that the pin is normally at the outer end of the slot. This is accomplished by the trip arm or lever from the trip rock-shaft, which at its extreme end beyond the lug or socket in which it rests is brought against the offsetting lug from the heel of the trip-fingers whenever the binding operation is finished by means of the rod and spring connection between the trip-dog and the crank on the end of the binder-shaft, whereby, as the latter is in its retrograde movement to withdraw the binder-arm beneath the table to its position of rest, which movement is caused by the pitman P from the gear and cam-wheel, it forces said dog against the lifting-finger upon the end of the trip-shaft, which is thus rocked and carries the outside trip arm or lever against said lug, whereby the tripfingers are swung inward as far as the slotand-pin connection with their supportingshaft permits them to go, and with precisely the same force which the accumulating gavel must overcome in order to again start the machine.

The slack-lever has heretofore been pivoted on the front board of the binder, sometimes called the wind boardfland its heel provided with a roller which traveled upon a cam on one of the idle-wheels driven from the trippinion, so that its front end would be raised or depressed at proper intervals to take up or give out slack in the cord which runs through an eye in the free end.

In Letters Patent No. 292,252, granted to the McCormick Harvesting Machine Company, January 22, 1884, as assignee of Henry E. Pridmore, was described and claimed a IIO slack-lever, acted upon at its heel end, which carried an anti-friction roller by a cam on one of the idle-pinions of the driving-train, and also having a tension-finger constantly resting upon and spring-pressed against the cord be tween the two guide-eyes at the free end of the lever. The cut-awayportion of this cam, permitting the lever to fall to yield up slack, was described upon an easy inverted curve, so as to offer no practical resistance to the travel of the anti-friction roller. The ten sion-finger being in constant frictional contact with the cord between the two guide-eyes of the lever, and the latter lying betweentwo fixed eyes on the frame, resulted in the free passage of said cord being obstructed when the binder-arm acted, and caused slack to be pulled alike from band and spool or other source of supply when the slack-lever rose.

\Ve now propose to so arrange the end of the tensionfinger q relatively to the end of the slack-lever Q as to bring the former outside of an inner eye or eyes, (1, thereon, and of the fixed eye or eyes on the frame, and above a lateral offset from said lever, which offset may be concave, as shown, and have an eye exterior to the finger, so that whenever the finger presses upon the cord this pressure shall be between the spool and said inner guide eye or, eyes of the lever. A casting, R, is secured to the front metallic frame-bar by slots and bolts, so that it may be adjusted slightly therealong, if found necessary, and from beneath this casting depends a hanger, 9', having a guide-eye, a", for the cord, which rises alongside of or between the inner eye or eyes of the slacklever when the latter is down. Above the casting, and integral therewith, rises a vertical ear, w, bearing a stubpivot, r, for the slack-lever, and a series of pins, '2", arranged concentrically with said pivot. coiled about this pivot-spindle, has one arm projecting up to be sprung in between any two of the pins, to increase or diminish its stress, and the other end arranged to press upon the tension-finger beyond its pivotal connection 0- with the slack-lever, thus at once forcing the tension-finger down upon or toward thelever, and through this finger exerting pressure upon said lever and holding its heel in constant contact with its controlling-cam. From the tension-finger depends a small stud, o which, on the descent of the lever, strikes and rests upon a lateral flange, r from the casting hanger, so that the finger is lifted from contact with the cord and the latter allowed to pull freely through while the lever is at the limit of its descent; but whenever the lever is lifted a sufficient distance to take up slack it strikes the tension-finger and carries that with it,

pressing upon the cord between the inner eye and the ball or spool. The slack, which is represented by a bight of cord extending between the two inner guide-eyes and the interposed stationary eye from the hanger, is consequently pulled entirely from the portion around the sheaf until the resistance becomes M) A spring, 0

so great as to overcome the tension, when it will also begin to pull from the spool or source of supply.

If the slack-lever and tension-finger had a common pivot, as in the just-mentioned patent, it is evident that the spring would no longer act upon the lever after the finger was stopped by the contact of its depending lug with the underlying flange, therefore we pivot the finger to the lever at a point along the length of the latter, between its own pivot and the guide eyes, thus obtaining a continuous effective action of the spring.

The cam S, which controls the slaclclever, is mounted upon the side of the first idlewheel in the driving-train, or that one in engagement with the trip-pinion on the drivingshaft, and while its general outline is the same as that heretofore employed, the cut-away portion, into which the roller 8 on the heel of the slack-lever falls at the moment the .binder is thrown out of operation and the stored up slack again yielded to the binder arm, is formed as a sharp re-entrant notch, s, of such outline as to practically embrace two sides of the roller and hold it firm against accidental displacement, so that said heel pressed forcibly up by the action of the spring upon the lever shall rise into the notch to hold the idle-wheel out of motion and steady the binding mechanism.

Of course it is not broadly novel to lock binding mechanism when out of action, since brakes'have been applied to various wheels; but in the present instance it will be observed the locking device is applied to the idle-wheel next to the driving-pinion, and is furnished by the slack-lever and its cam, thus placing double functions upon these instrumentalities.
